"Orthodox" means "right-teaching" and within the context of the GOP refers to the right-wing base of the larger Republican Party which is as a whole more conservative than orthodox. The right-wing base includes the whole "religious right", but is made up mainly of the "Christian right". Many people mistakely believe the Republican Party and the GOP are the same and on many levels it does appear that way since it can often be difficult to understand the constant flux of political alliances and postering within the parties, but the Republican Party is the larger "umbrella" party which covers many of the looser coalitions which are often only active during election years.

I registered as a Republican to reach out to more allies, but I'm actually with the GOP.

Greedy Oppressive Pricks the Republican Party which believes in low taxes for uberwealthy, increasing corporate profits by oppressing the working class and moving jobs overseas whenever possible. they also support oppressive social policies attempting to censor movies or music they don't like, restricting abortion, bashing gays, and making health care too expensive for most people to afford

The G.O.P. is so evil they don't even want children to have health care, George W Bush vetoed a children's health care bill.

Global Oppression Party;
Representing the current state of the US Republican right-wing dictatorship, under the puppetship of George W. Bush, lead exclusively by world banker families such as Rothschilds and Rockefellers, whose ultimate goal is to rule the world under a single government, controlling all aspects of lives, including monetary resources.

The GOPs next move: martial law in the US, sparked off by yet another in-sider's terrorist attack on US soil, to suspend elections, confiscate the firearms of all citizens, usher in a new North American Union including US, Canada and Mexico (to compensate the US Military with much needed meat shields), and to begin a conversion from the US dollar to the "Amero" fiat currency. I can't wait for Global Oppression! I'm going to get chipped-up right away!
